RAILWAY-TIE REPLAGER.

Specification of Letters Patent.

Application filed. March 21, 1911.

Patented Oct. 17, 1911.

Serial No. 615,990.

T 0 all whom it may concern:

Be it known that I, BENJAMAN S. OLSON, a citizen of the United States, residing at Little Falls, in the county of Lewis and State of l/Vashington, have invented certain new and useful Improvements in Railway- Tie Replacers, of which the following is a specification.

This invention relates to railway tracklaying appliances; and its object is to produce devices whereby decayed or worn track-ties may be readily removed by the substitution of new ones.

The invention consists in the novel construction and combination of devices as will be hereinafter described and claimed.

In the accompanying drawings Figure 1 is a side elevation of apparatus embodying my invention. Fig. 2 is a similar view of a portion of the same to an enlarged scale. Fig. 3 is a plan view of Fig. 2.

The reference numeral 5 designates a U-shaped frame having parallel members 6 which terminate in hook ends 7 arranged to engage over the flange 8 of a track-rail R.

Mounted for endwise movement on each of the frame members 6 is a sleeve 9 provided with offset projecting elements 10 to serve for engaging over the other flange 8 of a rail for supporting the machine therefrom, as illustrated in Fig. 1. The top and bottom edges of said frame members are serrated to furnish ratchet teeth 11 and 12.

Mounted on the frame is a carriage 13 having at its sides slotted lugs 14: to afford guide-ways to accommodate the frame members 6. Pivoted by a pin 15 to said carriage is a lever 16 carrying pawls 17 and 18 arranged to engage the ratchet teeth 11 and 12 respectively of the frame members when the lever 16 is oscillated to impart a step by step forward motion to the carriage. intermediate the frame members said carriage is provided with a plurality of forwardly projecting studs 19 which upon becoming embedded in the end of a tie T will serve to support the same.

The operation is as follows: When the machine is to be used for the purpose of introduoing a new tie in place of an old one, the hook ends 7 of the frame members 6 are engaged over the flange 8 of the rail It upon opposite sides of the old tie. The sleeves 9 are then moved forward to engage the rail flange 8 whereby the frame is supported by the rail in a horizontal position. The carriage 13 is then moved back to accommodate a new tie T which is inserted between the inner end of the carriage and the adjacent end of the old tie T (Fig. 1) from which the spikes have been withdrawn. By operating the lever 16 the pawls 17 and 18 are intermittently actuated to impart forward motion to the carriage urging the new tie forward and which, in turn, pushes the old tie thereinfront until the new tie has been moved to its required position under both rails R and R. lVliereupon the latter are spiked to the tie and the frame may be moved to anew station.

The invention is of simple construction and afi'ords means for uiokly substituting the tie of railway tracks without the necessity of any digging of the earth thereabout.

What I claim as my invention, is

1. A tie replacer comprising a frame adapted to be engaged with a track-rail, a carriage mounted on said frame for endwise movement, a lever carried by said carriage, and devices engaging said frame and actuated by the oscillation of the lever whereby movement may be imparted to the carriage for advancing the same toward the trackrail.

2. A tie replacer comprising a frame ar ranged to be engaged with a track-rail, a carriage movable longitudinally on said frame, means provided on said carriage to engage in the end of a tie for supporting such end, and manually actuated means whereby said carriage is moved to advance the same for imparting endwise movement to a tie.

3. A tie replacer comprising a frame having two side members provided with ratchet teeth and formed with hooked ends to engage a flange of a track-rail, a carriage mounted on the frame, a lever fulcrumed to a support on said carriage, pawls carried by the lever for coacting with the ratchet teeth of said frame members for advancing the carriage when said lever is oscillated.

4. A tie replacei' comprising a frame having two side members provided with ratchet teeth and formed with hooked ends to engage a flange of a track-rail, sleeves mounted for endwise movement on said frame members and adapted to engage the other flange of said track-rail, a carriage mounted on the frame, a lever fulcrumed to a support on said carriage, pawls carried by the lever for coacting with the ratchet teeth of said frame members for advancing the carriage when said lever is oscillated.

5. In a tie-replacer, the combination with a rigid frame, having two side members with teeth along the edges thereof and also provided with hooked ends to engage with a track-rail, of a carriage mounted for travel on said frame, and manually operable means carried by the carriage and cooperating 10 with said teeth whereby movement is afiorded to said carriage for the purpose of pushing a tie in front of the carriage as the latter Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
